Bubble in pressure gauge (Vevor DQT-3J)

[AntiRodentTaskForce]

I searched, but don't see a thread that mentions this issue, so here goes.

I bought a Vevor hand pump through amazon -- it dropshipped from China. I opened the box and unwrapped the pressure gauge. THe gauge is about 60mm in diameter, and inside there is oil (glycerin?) ... which has a 20mm bubble inside.

There is no trace of leakage -- the cardboard packaging is dry and unblemished. No stains.

• Should I ignore the bubble and use it anyway?
  or
• Should I return it, since this is a defect/problem?

It is perfectly normal for glycerin or oil filled gauges to have a bubble. I worked for a major fittings, valves and gauge manufacturer and it is normal. The bubble allows for some expansion of the liquid so as it does not eject the fill plug.

A number of mine have arrived that way, it will be fine.

Pressure gauges with liquid filling, such as glycerine, are mainly used in applications that involve high dynamic shock and vibration loading.

I’ve never seen one without a bubble.
